PLATO G. EMERY, OF CHICAGO, ILLINOIS.

SASH-LOCK.

To all whom it may concern:

Be it known that I, PLATO G. EMERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improven'ients in Sash-Locks, of which the following is a specification.

It has happened with some frequency that a passenger on a railway train has suffered serious injury by having a window sash fall on his hand or fingers and such accidents not only cause great suffering and sometimes permanent injury to the passenger but they have occasioned considerable loss by damages to the railway companies. It is a fact, also, that some persons have intentionally allowed a window sash to drop-on their fingers with the deliberate purpose of collecting` damages for the injuries sustained. l

It is my object to prevent a window sash from closing in a manner which will produce an accident of this kind and with this end in view I provide for closing the sash by an intermittent or step by step movement so that a passenger cannot, either accidentally or intentionally allow a sash to drop in such manner as to cause him injury.

The invention also has for its object to provide a sash lock which will permit the sash to be locked in any one of a number of predetermined positions and in such a manner that it can not drop to closed position without manual manipulation.

In the drawings Figure 1 is a general view of a window with the sash raised and showing by broken lines the several stopping'points or steps of the sash in lmoving to closed position. Fig. 2 is a vertical sec tional view on the line 2 2 of Fig. 3, showing the invention embodied in a metallic frame and sash. Fig. 3 is a transverse sectional. view on the line 8 3 of Fig. 2. Fig. l is an elevation showing a portion of the antirattling device; Fig. 5 shows the anti-rattling device of Fig. 3 arranged in a diiTerent position; Fig. 6 shows in transverse section a metal window frame in which one of the stops is made integral with the post; Fig. 7 shows both of the stops made inte gral with the post; Fig. 8 is a sectional View showing the invention embodied in a different form in a wooden frame and sash; Fig. 9 is a horizontal sectional view on the line 9 9 of Fig. 8; Fig. 10 is a detail front View of the locking bolt operating means Specification of Letters Patent.

shown in Figs. 8 and 9; Figs. 11, l2 and 13 are views similar to Fig. 3 but showing the invention in diierent forms; Fig. 14. is a vertical sectional view of a wooden stop; Fig. l5 illustrates another embodiment of the invention; Fig. 16 illustrates a shoulder plate used with the construction of Fig. 15.

In the drawings, 1 is the window sash, and 2 the posts, 3 the stops and 4f the sill of the frame. All these part-s may be made of metal, as shown on Sheet 1, or of wood, as shown on Sheet 2, or part of metal and part of wood.

Referring first to the metallic construction (Figs. 1, 3) the stops 3, 3, are preferably made in channel form and fastened to the post 3 in any suitable manner to form the guide groove for the sash. On their inner opposing sides the stops are provided with a plurality of shoulders 5 and between the shoulders the stops are slotted or otherwise constructed to form recesses G. Any number of shoulders may be provided on the stops but the shoulders on one stop should be arranged out of alinement with or in staggered relation to the shoulders on the other stop. A portion 5 of the metal cut out to form the slot above each shoulder may be bent inwardly to a horizontal position to widen the shoulder if desired. A portion 5 of the metal cut out to form the slot beneath each shoulder may be bent inwardly into an inclined position to form a guide, if desired. The locking device 7 is arranged within the sash 1 and it has a handle member 8 which projects through an opening 9 in the inner side of the sash (Fig. 3) and a locking bolt 10 formed by two lateral projections 11, 11 which are arranged to operate in openings 12 in the sash. A spring 18 is arranged within the sash to bear on the locking device and push it normally toward the inner side of the sash. The locking bolt is longer than the distance between the two stops of the window frame and the locking device is capable of moving laterally within the sash a sufficient distance to bring one or the other end of the bolt into position for operative engagement with a shoulder on the stops. In the construction illustrated in the drawings the end 11 of the locking bolt will engage a shoulder on the stop 3 when the locking device is pushed forward manually toward the outer side of the sash and against the pressure of spring 13; and when the manual pressure on the locking device is removed and the spring returns itl to normal position, as shown in Fig. 3, the end 11 of the locking bolt will engage a shoulder on the stop 3. Near the lower end of stop 3 I provide one or `more openings 14, 15, to receive the end 11 of the locking bolt, and the lower edge 14 of the opening 14 constitutes a shoulder similar to the shoulders The upper edge 15 of opening 15 constitutes a shoulder' with which the bolt engages to lock the sash in closed position. The stop 3 has a slot 6 located opposite these openings.

hen the sash is closed the end 11 of the bolt will project into the lower opening 15 to lock the sash. To open the window the operating handle is pushed in until the end 11 of the bolt is disengaged from opening 15 and the end 11 of the bolt is projected into the lower recess of the stop 3. The bolt is held in this position until the sash has been raised suificiently to carry the bolt above the opening 14 after which the handle may be released and the sash raised to its upper limit of movement. As the sash moves upward above opening 14 the end 11 of the locking bolt will engage. each inclined guide 5 which will force the bolt outward to clear the adjacent shoulder. After passing a shoulder on stop 3 the spring returns the locking bolt to position to clear the next 'shoulder on stop 3. Thus the locking bolt moves back and forth to clear the shoulders and the latter permit the sash to be raised without interference.

To lower the sash from the position shown in Fig. 2 the handle is pressed to disengage the bolt from the shoulder 5. If the manual pressure is removed from the handle as soon as the bolt moves with the sash below this shoulder the spring will ret-urn the bolt at once to the position shown in Fig. 2 and it will engage the next lower shoulder on stop 3 and its closing movement will be arrested until the handle is again manipulated. If the manual pressure on the liandle is not removed as just described t-he end 11 of the bolt will engage the next lower shoulder on stop 3 to arrest the sash. If the manual pressure on the handle is then removed the spring will return the bolt to normal position, disengaging it from the shoulder of stop 3 and thrusting it out to engage the next lower'shoulder on stop 3. The lower shoulders on stop 3 are preferably located close together so that each step in the closing movement ofthe sash will be short and also to provide for locking the sash in any one of several positions close together. Thus the sash is lowered by an intermittent or step by step movement to closed position, the shoulders on stop 3 controlling this movement when done properly and the shoulders on stop 3 preventing the sash from passing a shoulder on stop 3 without stopping. In this construction the lock will be provided at one side only of the sash, but it may be duplicated at the other side if desired.

I provide an anti-rattling device for holding the sash tightly against one of the stops and also to exclude dirt, etc., as far as possible. I prefer to apply this device on the inner stop 3 and it-comprises an angular plate 17 (Fig. 3), of which one member -17 is clamped securely in place between the stop 3 and the post 2 and the other member 17 is inclined and lies between the stop andthe sash 1. The outer edge of the member 17 bears against the sash and pushes it against the stop 3 to make a snug fit and tight joint between the sash and the stop. The member 17 is provided with slots 1S and shoulders 18 to correspond with the slots 6 and shoulders 5, and with openings 19 and shoulders 19 to correspond with the openings 14, 15 and shoulders 14, 15, on the stop 3.

In Fig. 3 the anti-rattling device is shown clamped between the stop 3 and the post 2 by the attaching screws 2O but this device may be fastened as shown in Fig. 5. Or the. inner shouldered and slotted side ofy the stop itself may be bent inward to form the antirattling means as shown at 21 in Fig. 6. In the latter construction filler blocks 22 are preferably provided wit-hin the stop at the screws 2O to support the stop.

In the metallic construction heretofore described the locking bolt operates transversely through the sash and engages shoul ders at the sides of the stops. In Figs. 8-10 I have shown another embodiment of my invent-ion in which the locking device comprises a bolt 23 which extends through an opening 24 in the lower part of a wood sash and is somewhat longer than the width of the sash so that its ends will engage shoulders 25 alternating with recesses 26 in the posts at the back of the guide grooves between the stops. A spring 27 is suitably housed within the sash and operates on the bolt to normally project one end thereof into position to engage a shoulder 25 in the right hand post ofthe frame. In the con- 115 struction shown in Figs. 3 and 9, means are provided to move the bolt against the pressure of spring 27 to project the other end of t-he bolt into position to engage a shoulder in the left hand post. This operating 120 means may comprise an angular yoke 28 'pivoted at 29 within a chamber 30 in the sash. The yoke engages shoulders 23 on the bolt and it has a handle 31 which projects through a slot 32 in the face plate 33 125 f fastened on t-he'sash over the chamber 30.' This face plate has a flange 34 which may be grasped by the operator to facilitate the manipulation of the handle. In this construction the operation is similar to that previously described but the bolt operates lengthwise of the sash insteadl of transversely and one set of shoulders is located in one guide groove, at the back thereof, and the other set in the other guide groove, at the back thereof, instead of both sets in the sides of one guide groove.

In Fig. 11 I have shown the locking device of Figs. 2 and 3 in a wood frame.

In Fig. 12 the locking device is made in the form of an angle lever 35 pivoted in the sash at 35', o-ne end projecting outward to form a handle 36 and the other end 37 o'peratively engaged with a slot 37 in the bolt 38. In Fig. 13 the locking device is also made in the form of an angle lever 39 pivoted at 40 in the frame and having on one end an integral bolt 41 curved on the arc of a circle. In the constructions of Figs. 12 and 13 the springs 42 and 43 are located on the inner side of the locking device to hold the handles in more convenient position, in these particular' constructions, for operation, and of course the shoulders would be reversed so that those on the outer stop of Fig. 2 would be located on the inner stop. In this connection it may be said as to all the constructions that the same reversal of position is possible if the locking device is set accordingly.

In Fig. 14 I have shown part of a wood stop 44 for use with the locking devices of Figs. 11-13, the shoulders 45 being formed between the recesses 46.

My invention may be embodied with a window frame of common construction comprising a wood post 47 and stops 48 (Fig. 15) without changing the form of the stops or the posts to provide the shoulders and recesses heretofore described, as illustrated in Figs. 8 and 9. In this adaptation of the invention the shoulders 49 are formed on plates 50 which are fastened to the stops as shown in Fig. 15. Theseshoulders 49 correspond, to all intents and purposes, with the shoulders heretofore described and the space between each pair of shoulders on each stop constitutes the recesses which correspond tothe recesses heretofore described. 'Ihe locking device 51 may be of any of the forms heretofore described and it is located so that the bolt 52 isarranged in operative relation to the shoulders 49.

It will be readily understood by those skilled in the art that the invention can be embodied in a window sash and frame in various combinations of wood and metal and therefore I do not restrict myself to the particular material of which any of the parts are made. One or both of the stops may be formed integral with the post, whether made of metal or wood, and in Fig. 6 I have shown a stop 53 made integral with the metal post 54, the other stop 55 being removable to facilitate the insertion and removal of the sash. In Fig. 7 I have shown both stops 56 made integral with the metal post 57.

I prefer to employ the spring in connection with the locking device but it may be omitted if desired for the bolt is longer than the distance between the ver-tical planes of the edges of the shoulders and hence it is in position at all times to engage a shoulder at one or the other end.

My invention is simple in construction and inexpensive to make. It can be readily applied to cars now in service by simply changing the stops and locking devices. It compels the lowering of the sash by an intermittent step by step movement and the lower step is short so that no injury will be caused even if the passenger does stick his finger beneath the sash. It is necessary for the passenger to manipulate the locking device to lower the sash from one step to the next and it is this manipulation which protects him against injury.

I may provide only one opening at the lower end of stop 3 with which the bolt will engage to lock the sash or I may provide a` plurality of openings or a plurality of the shoulders 5 to insure a succession of short stops in the movement of the sash to closed position as it nears the sill. As heretofore explained the invention can also be applied to window frames without changing the stops by using the shoulder plates as illus trated in Figs. 15 and 16. The inclined guides beneath the shoulders are provided to enable the sash to be raised, after it is unlocked, without manipulating the locking device as is necessary in closing the sash for, as before explained, the bolt will be operated by engagement with said guides to clear the shoulders on the upward movement of the sash, and these guides may be formed in any suitable manner.
